You can compress datasets in a file geodatabase to save space, but doing so makes the datasets read-only. If the data in your file geodatabase is edited frequently, consider compacting the file geodatabase to clean up storage and unused space and, thereby reducing the geodatabase size. To control how other people use the data you share with them in a file geodatabase, you can apply a license to the file geodatabase before you give it to them.
Feedback on this topic? Back to Top. Datasets File geodatabases contain system tables that provide geodatabase functionality plus the data you add to the geodatabase.
They can be virtually unlimited in size and number of users; the limits differ depending on the database management system DBMS vendor. A collection of various types of GIS datasets held as tables in a relational database.
A collection of various types of GIS datasets contained within a relational database. A collection of various types of GIS datasets held in a file system folder. All the datasets that belong to one mobile geodatabase are contained in an SQLite database that is stored in a single file.
Each dataset is a separate file on disk. All the datasets that belong to one geodatabase are contained in a single folder. By default, each dataset can grow to 1 TB. The 1 TB limit can be raised to 4 or TB for extremely large image datasets.
Each feature class can scale up to hundreds of millions of vector features per dataset. Supported across all database management systems. Operating system support depends on the DBMS you use. Most support multiple operating systems. Consult the documentation for your DBMS for the full list. File geodatabases are freely available to all users of ArcGIS Pro and are designed to support the full information model of the geodatabase, which comprises network datasets, terrain datasets, relationship classes, and so on.
File geodatabases are designed to be edited by a single user and do not support geodatabase versioning. With a file geodatabase, it is possible to have more than one editor editing at the same time provided they are editing in different feature datasets, stand-alone feature classes, or tables. The file geodatabase is ideal for GIS projects, personal use, and in small organizations.
It has strong performance and scales well to hold extremely large data volumes without requiring the use of a DBMS. Additionally, it is portable across operating systems.
You can employ multiple file geodatabases for your data collections and access these simultaneously for your GIS work. Mobile geodatabases are automatically available to all users of ArcGIS Pro and expose the geodatabase functionality required to work with simple data using domains, subtypes, and relationship classes.
Functionality available within a mobile geodatabase includes contingent values, relationship classes, editor tracking and use of attachments. Mobile geodatabases are designed to be edited by a single user and do not support geodatabase versioning. This comprehensive information model is implemented as a series of tables holding feature classes, raster datasets, and attributes.
In addition, advanced GIS data objects add GIS behavior; rules for managing spatial integrity; and tools for working with numerous spatial relationships of the core features, rasters, and attributes. Geodatabase software logic provides the common application logic used throughout ArcGIS for accessing and working with all geographic data in a variety of files and formats.
Geodatabases have a transaction model for managing GIS data workflows.
